attach the core dump please? I've got this installed on a beaker system with kernel 4.18.0-51 and rng-tools-6.6-1 and its running fine, so a more detailed reproducer is also needed here. Alternatively, if you can provide access to the system in question, that would help (In reply to Neil Horman from comment #2) > I've got this installed on a beaker system with kernel 4.18.0-51 and > rng-tools-6.6-1 and its running fine, so a more detailed reproducer is also > needed here.

From the sched_getaffinity man page: EINVAL The affinity bit mask mask contains no processors that are currently physically on the system and permitted to the thread according to any restrictions that may be imposed by cpuset cgroups or the "cpuset" mechanism described in cpuset(7). EINVAL (sched_getaffinity() and, in kernels before 2.6.9, sched_setaffinity()) cpusetsize is smaller than the size of the affinity mask used by the kernel. We're seeing an EINVAL errno on the call to sched_getaffinity, so one would presume that either we are using too small a cpu set mask or something in the cgroup configuartion is erroneously creating a zero affinity mask. I can't believe the problem is a too small cpusetsize, as the cpusetsize is computed by asking the kernel what the size should be via the sysconf call. I tried to hope back on to the vm to provide more detail, but it seems the system is no longer setup in the same way. Can you re-establish it please so that I can look more closely?

Thanks, yduan I can work on this again, please restart the vm thank you, but unfortunately the problem does not reproduce now, even if my patch is not applied, so there must be something different about this setup (In reply to Neil Horman from comment #28) > thank you, but unfortunately the problem does not reproduce now, even if my > patch is not applied, so there must be something different about this setup Hi Neil, I can still meet it in the VM.

I don't see libvirtd running > on the host Yes, you can find the qemu command line in host through "ps aux | grep qemu". BR, yduan ------- Comment From cborntra.com 2019-01-11 02:52 EDT------- For what its worth, I saw this problem in an LPAR. Thank you, I think that may be the root of the reproducer. All the systems I've tested on that are virt systems have the number of cores equal to the number of cpus on the bare metal system, and this guest is started with -smp 8,maxcpus=240. Thats probably causing the sysconf call in rng tools to return 8 (thereby allocating 8 cpus in the affinity array, but getaffinity would require 240 entries to not fail. Thats how you reproduce the problem, by forcing there to be fewer cpus configured than the max number FWIW, I have seen this problem in an s390x LPAR (not a KVM guest). (see IBM bug 174583 - RH bug 1665057) ------- Comment From cborntra.com 2019-01-14 06:10 EDT------- snapshot 1 was still ok (it has rng-tools-6.2-1.el8 instead of rng-tools-6.6-1.el8) ------- Comment From cborntra.com 2019-01-14 06:17 EDT------- FWIW, the same would be true on LPAR. My LPAR has 32 processors, but the maximum value is higher. ------- Comment From Christian.Rund.com 2019-01-22 15:31 EDT------- *** Bug 174884 has been marked as a duplicate of this bug. *** Thanks.
